Smoke circulating combusting system for waste palm boiler

Abstract

The invention provides a smoke circulating combusting system for a waste palm boiler. The system is that a fire grate comprises a drying section reciprocating fire grate and a combustion section reciprocating fire grate which are connected through continuously-inclined staggering disconnecting layers; inclination angles of the drying section reciprocating fire grate and the combustion section reciprocating fire grate are 20 to 30 degrees; a plurality of primary air branch tubes and a plurality of smoke circulating branch tubes are arranged in the drying section reciprocating fire grate and the combustion section reciprocating fire grate, wherein the primary air branch tubes and the smoke circulating branch tubes are respectively communicated with an air preheater and a tail smoke channel through primary air head tubes and smoke circulating head tubes; the tail smoke channel, the smoke circulating head tubes, the smoke circulating branch tubes, the smoke circulating branch tubes, a hearth and a smoke outlet are sequentially communicated by a circulating manner; the air preheater, the primary air head tubes, the primary air branch tubes and the hearth are sequentially communicated by circulating. The system can solve the problems of unstable combustion of the hearth and coking, and achieves efficient, energy-saving and safe operation of the waste palm steam boiler.

Description

technical field [0001] The invention belongs to the field of boilers, and relates to a palm waste combustion technology, in particular to a palm waste boiler flue gas circulation combustion system. Background technique [0002] With the progress and development of society, people's awareness of energy conservation and environmental protection is increasing day by day, and the international community has higher and higher requirements for energy conservation and emission reduction. Energy has attracted widespread attention from various countries because of its cheapness and renewable nature. Biomass fuel has become an important part of the sustainable development strategy of countries all over the world. It can provide the government with a win-win energy solution, and it also reduces the dependence on crude oil from distant, politically unstable or even dangerous countries, which is conducive to energy security. . It is of great significance to achieve the global goal of e...

Problems solved by technology

It solves the problem that the traditional incineration boilers in the prior art use palm slag as fuel. The fuel is easy to bridge, block, and temper in the silo, and it is easy to cause serious ash accumulation on the heating surface of the incineration boiler and its tail, which will damage the incineration boiler and make its tail Defects of corrosion on the heating surface
